Rule
Summary
Starting September 30, 2026, new Cuba Sanctions Regulations kick in to enforce tougher U.S. rules against Cuba’s government for actions threatening U.S. security.

More detailed guidance and licenses will come later, so watch for updates that could impact money and trade.
Analyzed Economic Effects
8 provisions identified: 3 benefits, 5 costs, 0 mixed.
Broad prohibition and asset blocking
Starting September 30, 2026, all transactions prohibited by Executive Order 14404 are prohibited under the new Cuba Sanctions Regulations. Persons designated under E.O. 14404 will have their property and interests in property blocked and their names published and incorporated into OFAC's Specially Designated Nationals and Blocked Persons List (SDN List) using the identifier "[CUBA-EO14404]".
Blocked funds must be held in blocked accounts
U.S. persons holding funds subject to Sec. 516.201 must place those funds in a blocked interest-bearing account in the United States (or, in some circumstances, keep them in existing foreign accounts). Blocked funds may not be invested in instruments maturing more than 180 days, and may not be used to provide benefit or access to blocked persons.
Willful violations may bring criminal penalties
Willful violations of the Cuba Sanctions Regulations may be subject to criminal penalties pursuant to 50 U.S.C. 1705; the statutory mens rea for criminal liability is willfulness.
Transfers of blocked property are void
Any transfer after the effective date that involves property blocked under Sec. 516.201 is null and void and cannot create or recognize any interest or right in that property. Also, judicial processes (attachment, judgment, garnishment, etc.) are null and void against blocked property unless licensed.
Foreign banks may be barred from U.S. correspondent accounts
OFAC will add names of foreign financial institutions subject to prohibitions or strict conditions on opening or maintaining correspondent or payable-through accounts in the United States to a CAPTA List on OFAC's website and publish those listings in the Federal Register.
Emergency medical and NGO humanitarian transactions authorized
The rule authorizes the provision and receipt of nonscheduled emergency medical services that would otherwise be prohibited, and it authorizes transactions ordinarily incident and necessary to nongovernmental organizations' non-commercial activities that directly benefit the civilian population (including humanitarian projects, food or medicine distribution, health services, assistance for vulnerable populations, and democracy-building activities), provided the NGO is not itself blocked.
OFAC licensing pathway and payment routing rules
OFAC may issue general and specific licenses to permit otherwise-prohibited transactions; licenses will be available in subpart E or on OFAC's website. Payments routed through the U.S. financial system should reference the relevant OFAC license to avoid blocking or rejection of the transfer.
Legal counsel and payment rules for blocked persons
Provision of certain legal services to blocked persons (advice on U.S. law, representation in U.S. proceedings, and related services) is authorized, but payment of fees from funds must follow Sec. 516.507: payments may come from funds originating outside the United States and not from U.S. sources, funds controlled by U.S. persons, or funds of other blocked persons. Recipients must retain payment records for ten years.

This means certain transactions that were blocked before are now allowed temporarily, as long as payments to blocked accounts follow the rules. If you’re dealing with CCU Bank or its big owners, this gives you a clear deadline to wrap things up without breaking the law.
